Delfi-C3 HEARD over the Delfi-C3 groundstation 08:53 UTCpass - s/c in EMERGENCY mode



Hi all,

we just heard Delfi-C3 again over the Delfi-C3 groundstation on the 08:53
pass. Signal was strong, NORAD Object #32786 seemed to fit best, but we are
not 100% sure.
Judging from the downlink, the spacecraft is in emergency mode.
TLE's for object #32786:

1 32786U 08021D   08119.87805543  .00000721  00000-0  10000-3 0   115
2 32786 097.9993 179.9103 0012861 292.3044 067.6803 14.80984919   100

Frequency: 145.930MHz
Downlink signal in emergency mode are 2 tones, of 500Hz and 900Hz each,
modulated DSB onto the (suppressed) carrier, use USB to receive this signal.
These tones themselves are modulated with 100Bd FSK each with raw payload
data. If you hear this signal, please record a wav file if possible.

If you hear Delfi-C3 please send your reports to

missioncontrol@delfic3.nl

stating AOS, LOS, frequency, signal strength
If possible, please record and attach a WAV file

Thanks!
